How to play Modern Combat 4 with a PS3 Sixaxis controller

"Gameloft put Modern Combat 4: Zero Hour on sale for $1 yesterday. Now is the perfect time to purchase what is arguably the best military first-person shooter for Android. Unfortunately, Modern Combat 4‘s default touch screen controls can’t emulate the precision that a real controller offers. The MOGA controller is supported, but Modern Combat 4 doesn’t have an option that allows other third-party controllers. That’s where an app called Sixaxis Controller comes in handy. It only works for rooted Android devices, but it will allow you to map Modern Combat 4‘s virtual buttons to a PS3 Sixaxis controller."
